Does A2 Hosting support WebSocket connections?

The WebSocket protocol provides persistent, two-way communication between a browser and a server over a single TCP socket. This enables web applications to be responsive in real-time, without the need to poll a server for new information.

A2 supports WebSocket connections on the following hosting packages:

  • Managed VPS and Dedicated servers: If you want to run WebSockets on these hosting packages, and do not have root access, please open a support ticket on the A2 Hosting Customer Portal at https://my.a2hosting.com and we will set up the server for you. In the ticket, please provide the following information:
    • The domain or URL you want proxied for the WebSocket application.
    • The port number on which you want WebSockets to run.
  • Unmanaged VPS: This hosting package provides you with root access and complete control over the operating environment. You can configure and run WebSockets independently.
  • For detailed information about how to configure and use WebSocket connections, please see this article.
  • A2 does not support WebSockets on shared or reseller hosting packages at this time.
